Our Verdict
A warm and cosy down bag reduces cold spots and drafts from entering the bag. 625g of Down Tek™ and a fill power of 650 gives Greystone 20 comfort limit of -7°. It’s a generous-sized bag with plenty of room to toss and turn without the bag feeling constrictive. The Greystone has a nice well-fitting hood, an oversized interior anti-draft collar and an insulated tube along the hood, which all increase the bag's warmth, and prevent cold air from entering the bag.
This is an excellent 4 season bag, -7°C protection (with a good mat and good thermal layering) at a very reasonable weight and price!
